Claims.

The present invention relates to door constructions in general and moreparticularly to an improved door of the type including a wooden framewhich is either partially or wholly encased in metal.

An object of the invention is the provision of a door of this characterwherein the metallic covering for the wooden frame is composed ofextruded metal strips of substantially channel formation associated withand secured to the wooden frame in such a manner that the securing meansfor said metal strips are not visible when the door is closed.

Another object of the invention is the provision of a door of thischaracter including means for loosely connecting the extruded metalStrips at their adjacent ends in a manner to permit relative expansionand contraction between the wooden frame and metallic covering thereforat the corners of the door.

A further object of the invention is the provision of a door of thischaracter of neat, attractive appearance, which is extremely easily andsimply fabricated, and which is provided with novel means for readilyand conveniently mounting a pane of glass therein.

A still further object of the invention is the provision of means formounting a pane of glass in the door so constructed that the securingmeans therefor are positioned upon the inside of the door andinaccessible from the outside when the door is closed.

Other objects and advantages of the invention will become more apparentduring the course of the following description, when taken in connectionwith the accompanying drawings.

In the drawings, wherein like numerals are employed to designate likeparts throughout the same:

Fig. 1 is a front elevation of a door construction provided by theinvention;

Fig. 2 is a vertical transverse section through the door takensubstantially on line 2-2 of Fig. 1 with the transom bar and door frameremoved;

Fig. 3 is a horizontal transverse section taken substantially on line 33 of Fig. 1;

Fig. 4 is a horizontal transverse section taken substantially on line4-4 of Fig. l;

Fig. 5 is an enlarged sectional view of the mounting for the pane ofglass; and

Fig. 6 is a detail section taken substantially on line 6-6 of Fig. 1.

In the particular embodiment of the invention disclosed in the drawings,as illustrative ofv one form which the present invention may take,

there is shown a so-called entrance type of door including the doorproper I0 above which is arranged the transom II. The-door I0 andtransom I I are mounted in the customary door .lamb including thevertical side members I2 and I3 and the horizontal head member I4.Arranged between the top of the door I0 and bottom of the transom II isthe usual transom bar I5.

The doorv II) comprises a wooden frame of the desired shape and sizeincluding the vertical stiles I5 and Il and the horizontal top andbottom rails E8 and I5 suitably connected together at their adjacentends to form a substantially rigid frame. rfhe outer surfaces of thewooden stiles I6 and I1 are covered by metallic strips 2I and 22respectively provided with rearwardly directed flanges 23 and 24 whichoverlap the opposite side edges of said stiles as best shown in Fig. 3.The opposite side edges of the stiles are preferably notched as at 25and 26 to receive the flanges 23v and 24 respectively of the metallicstrips. It will thus be seen that the strips 2I and 22 are ofsubstantially channel formation and they are preferably formed ofextruded metal such as aluminum of relatively heavy gauge. The metalchannel strips are secured to the wooden stiles by screws or the like 21which pass through the flanges 23 and 24 thereof.

The top rail I8 of the wooden frame also has its outer surface coveredwith a similar metal channel strip 28 and this strip is provided withrearwardly turnedflanges 29 and 30 which overlap the upper and loweredges of the rail and are secured theretoY by screws or the like 3I. Themeeting ends of the vertical channel strips 2| and 2.2 covering thewooden Stiles I6 and II and the horizontal channel strip 28 covering thewooden top rail I8 are preferably mitered at their adjacent ends as at32 and 33.

The bottom rail I9 of the wooden frame is here shown as beingconsiderably wider than the top rail I8 andV is covered by the upper andlower horizontal angle strips 34 and 35 also preferably of extrudedmetal and spaced from one another to receive therebetween a metal kickplate 36. The upper angle strip 34 is provided with an inturned ange 31which overlaps and is secured to the upper edge of the bottom rail byscrews or the like 38, while the lower angle strip 35 is provided withan inturned flange 39 overlapping the bottom edge of the rail andsecured thereto by screws or the like 40.

The inner adjacent longitudinal edges of the angle strips 34 and 35 arespaced from one another as best shown in Fig. 2 and are formed withgrooves 4I and 42 respectively within which the kick plate 36 isslidably received. The inner adjacent marginal edge portions 43 and 44of the angle strips 34 and 35 overlap the front surface of the kickplate while the said strips are also formed, in back of the kick plate,with plate portions 45 and 46 respectively secured to the rail by screwsor the like 4'I. 'Ihe kick plate 36 and plate portions 45 and 46 arepreferably set into a recess 48 in the front surface of the wooden railI9.

In the construction of the door, the inner flanges 24 of the metalchannel strips 2l and 22, covering the wooden stiles I6 and I'I, extendfrom the top of the door down to the top of the bottom rail I9 only,while the strips 2| and 22 and outer flanges 23 extend downwardly to thebottom of the door as shown in Fig. 1, with the said strips overlappingthe opposite end edges of the kick plate 36, as shown in Fig. 4. Thoseportions of the metal strips 2| and 22 extending beneath the bottom railI9 can be secured to the wooden stiles I6 and Il by screws or the like49 passing through anges 23. The lower ends of the metal strips 2l and22 and opposite ends of the metal angle strip 35 are mitered as at 50and 5I.

To provide for relative expansion and contraction between the woodenframe and the metal covering therefor at the corners of the door, thereis provided at each of said corners a substantially H-shaped stripbeading 52 (Fig. 6) also of metal. This beading is provided with twooppositely disposed grooves 53 and 54 adapted to loosely receive theadjacent ends of the respective metal strips. The beading 52 is notsecured to the wooden frame but simply fits in a recess 55 therein.Consequently, upon relative expansion and contraction of the woodenframe and metal covering, the meeting ends of adjacent metal strips arefree to move inwardly or outwardly within the grooves 53 and 54 of thebeading 52.

The door is also provided with a window 56 consisting preferably of asheet or pane of glass mounted in the door by means of a metal frameincluding the top and bottom sections 'I and 58 and side sections 59 and66. Since all of the metal frame sections are of the same construction,a detailed description of only one will be given. As best shown in Fig.5, each metal frame section comprises an outer member 6I and an innermember 62. The outer member 6I includes a front portion 63 extendingsubstantially parallel with the glass sheet 56 and a base portion 64extending rearwardly at right angles thereto and beyond the edges of thepane of glass. The base portion 64 is secured to the inner edge of therespective stile or rail of the Wooden frame by screws 65, while thefront portion 63 is preferably provided along its outer edge with a bead66 engaging the outer surface of the glass sheet. The front portion 63of the outer member 6I is also provided with a forwardly directed flange6'I of any desired profile. 'I'his flange 6'I not only forms anornamental molding or edging but also serves to cover the attachingscrews 38 for the metal angle strip 34.

The inner member 62 comprises a rear portion 68 provided along its outeredge with a bead 69 engaging the inner surface of the glass sheet '56.The inner member 62 is also provided with an inwardly turned baseportion 'I6 which rests upon the base portion 64 of the outer member 6Iand is secured thereto by screws 'II. rl'fhe base portion 'I0 of theinner member is preferably provided with transverse slots 'I2 throughwhich the screws 'II pass. This permits the inner member 62 to be movedinwardly or outwardly to accommodate glass sheets of differentthicknesses. When installing the window, the outer members 6I are rstsecured in place. The pane of glass 56 is then positioned to engage thebeads E6, after which the beads 69 of the inner members 62 are movedinto contact with the inner surface of the glass sheet and the screws 'II' put in place and tightened.

The transom II may be and preferably is of substantially the sameconstruction as the door I il and also includes a window 'I3 mounted inthe same manner as the window 56 is mounted in the door. The transomcomprises a substantially rectangular wooden frame including the top andbottom members 'I4 and l5 and similar side members (not shown). Each ofthe members of the wooden frame has its outer surface covered by a metalchannel strip '16, the inturned flanges l1 and 'I8 of which overlap theedges of the frame member and are secured thereto by screws or the like79. The meeting ends of the channel strips 'I6 are also preferablymitered as at 66 and may be secured together by metal strip beading suchas shown in Fig. 6. The pane of glass 'I3 constituting the window may besecured in the transom frame by means of a metal frame mountingincluding the top and bottom sections BI and 82 and side sections 63 and64. Since the metal frame sections are the same as illustrated anddescribed above for mounting the pane of glass 56 in the door, it is notbelieved necessary that they need be described in detail.

As brought out above, the metal strips used for covering the woodenframe of both the door proper I0 and transom II are of extruded stock,

.preferably of relatively heavy gauge, which results not only in astronger, more durable construction, but also in a door of pleasing,attractive appearance. It will of course be appreciated that while onlythe front faces and approximately one-half of the side edges of thewooden frame members have been illustrated as being covered, the woodenframes may be entirely encased with metal if desired. Also, ifpreferred, the kick plate 36 may be omitted, in

which case the angle strips 34 and 35 could be made integral with oneanother in the form of a single channel strip. By securing the metalcovering strips to the wooden frame members in the manner disclosed, thesecuring means for said metal strips will not be visible when the dooris closed. Likewise, `the fastening screws 'II of the metal framemounting for the pane of glass 56 are positioned upon the inside of thedoor and in this way prevent removal of the glass from the outside.

It is to be understood that the form of the invention herewith shown anddescribed is to be taken as the preferred embodiment of the same, andthat variousv changes in the shape, size and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claims.
